I want to try a UART communication without RTS & CTS my board is PCA10001, and I use the SDK 6.1 example: uart_example.
I use Serial Port Utility to communicate with the board by onboard usb port. It is all fine to run the example. To run without RTS & CTS I redefine HWFC as false in PCA10001.h After reload and download, I try again the communicate I receive the string "Start:" in window as normal, but I can't receive any reply after I sending a word What should I do to make it work?
